新增服務以傳送通知
在本部分中,我們將使用Android Notification Manager傳播從Adobe Campaign收到的訊息。 Notification manager用於通知使用者發生的事件。
這是您告訴使用者背景中發生某些事情的方式:
- 啟動Android Studio
- 開啟 ACSPushTutorial 專案
- 展開專案結構
- 用滑鼠右鍵按一下封裝資料夾(com.example.acspushtutorial)和New ->Java Class
- 命名這個類別 MyService 並確定它擴充FirebaseMessagingService
- 在此類別中建立 sendNotification 方法。 在此方法中,您需要使用NotificationCompat.Builder物件來設定通知的內容和通道。 若要讓通知出現,請呼叫NotificationManagerCompat.notify(),為通知傳遞唯一識別碼,並傳回NotificationCompat.Builder.build()的結果。
package com.example.pushmessaging;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Build;
import android.util.Log;
import androidx.core.app.NotificationCompat;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import java.util.Map;
public class MyService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
Map<String,String> data = remoteMessage.getData();
Log.d("data payload: ", data.toString());
sendNotification(remoteMessage);
}
private void sendNotification(RemoteMessage message) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT);
String channelId = "0";
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_launcher_background)
.setContentTitle("Message from AEM")
.setContentText(message.getData().get("body"))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
修改AndroidManifest.xml
將已建立的服務新增至您的AndroidManifest.xml。 最終AndroidManifest.xml應該如下所示:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.pushmessaging">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:name=".MainApp"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<service
android:name=".MyService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
